Title: Structure of spindle of drilling machine
Inventor: NISHIZAWA SHIGERU
IPC: B23B47/18
Filed: 1979-10-30
Abstract: PURPOSE: To prevent the breakage of a drill by a method wherein a spindle whose housing for the drill is devised to have a double structure is used and the drilling pressure is fixed through the adjustment of pneumatic pressure.  
     CONSTITUTION: The pressure F acting on the housing 12 is adjusted through the regulation of the pressure of compressed air 17. When the main shaft head 22 is lowered at a fixed speed by a motor 23, the drill 25 chucked by a drill chuck 10 starts to cut an article to be sut. As the drilling pressure rises with the increase of cutting resistance, the drill 25 turns out to be pressed by the housing pressure F irrespective of the speed of a cylinder 15. Since the drilling pressure is set not to exceed a prescribed value through the adjustment of the compressed air, the breakage of the drill is prevented.

Title: Digital demodulator
Inventor: KANI NOBUHIRO
IPC: H04B1/26
Filed: 1998-05-21
Abstract: PROBLEM TO BE SOLVED: To enable digital demodulation without generating any error even when a lot of channels are sent to a narrow band by inserting an amplifier circuit between a detection circuit and a base band filter and reducing the input of the detection circuit so as to complement the amplification factor of the amplifier circuit. SOLUTION: In order to deal with a lot of channels, I and Q detection is required within a narrow frequency range so as not to erroneously receive the other channel. Therefore, an I/Q detector 15 is provided with a local oscillation circuit 21 using a crystal oscillator. Then, an amplifier circuit 16 is inserted between the I/Q detector 15 and a base band filter 17, and the input of the I/Q detector 15 is reduced so as to complement the amplification factor of the amplifier circuit 16. Thus, since the input of the I/Q detector 15 is reduced so as to complement the amplification factor of the amplifier circuit 16, even when a lot of channels are sent to the narrow band, no distortion occurs at the I/Q detector 15 because of a low input level.
